S4 (B+) and the 5th fragment S5 (B+) for separating for 1/4 cycle in circumferential R side R1 relative to the 4th fragment S4 (B+).Cause
This, the second fragment S2 (B+) separates 1/2 cycle, the 3rd fragment S3 (B relative to the 5th fragment S5 (B+) in circumferential R side R1
+) relative to the 4th fragment S4 (B+) circumferential R opposite side R2 separate 1/2 cycle.Here,+B is mutually with sense magnetic pattern 570B+
Mutually it is alternately arranged with-A with sense magnetic pattern 570A- each fragment circumferentially, such as the 4th fragment S4 (B+) is relative to the 4th fragment
S4 (A-) separated for 1/8 cycle in circumferential R opposite side R2.In+the B so formed mutually uses sense magnetic pattern 570B+, the first fragment
S1 (B+), the second fragment S2 (B+), the 3rd fragment S3 (B+) and the 4th fragment S4 (B+) are in terminal 572Vccf and terminal
Connected between 572GND.Also, terminal 572B+ is connected electrically between the 4th fragment S4 (B+) and the 5th fragment S5 (B+), terminal
572Vccf is connected with second fragment S2 (B+) side, and terminal 572GND is connected with the 3rd fragment S3 (B+) side.Such composition+B is mutually used
Half bridge circuit.In+the B so formed mutually with sense magnetic pattern 570B+, the 4th fragment S4 (B+) is with-B mutually with sense magnetic pattern
570B+ the 5th fragment S5 (B-) is co-located in circumferential R, but from the unilateral observation for being connected with terminal 572B+, 572B-
When, the 4th fragment S4 (B+) is mutually located at circumferential R opposite side with-B with sense magnetic pattern 570B+ the 5th fragment S5 (B-).Therefore,

Magnetic pattern 570B- respectively have circumferential R separate 1/2 cycle the first fragment S1 (the 4th fragment S4 and the 5th fragment S5),
Second fragment S2 and the 3rd fragment S3.Therefore, it is possible to suppress to make detection because of the coercivity of the sense magnetic pattern of magnetoresistive element 57
Signal is deformed.For example, in+A mutually uses sense magnetic pattern 570A+, due to forming the first fragment S1 (A+) the 4th fragment
During S4 (A+) and the 5th fragment S5 (A+) and N extremely opposed, the second fragment S2 (A+) and the 3rd fragment S3 (A+) and S are extremely right
Put, therefore even if the coercivity of the sense magnetic pattern of magnetoresistive element 57 has the characteristics such as polarity asymmetry, can also suppress to make detection
Signal is deformed.Also, because the first fragment S1 (the 4th fragment S4 and the 5th fragment S5) both sides are configured with second
Fragment S2 and the 3rd fragment S3, therefore can shorten in magnetoresistive element 57 and be configured with A phases sense magnetic pattern 570A and B phase
With the circumferential R in sense magnetic pattern 570B region size.

With the screw 539 that the side of supporting mass 200 can be movably maintained to the bending direction of spring members 75 (helical spring 76)
(screw component).Therefore, it is possible to be easily adjusted snap fastener 7a load, and easily assembling snap fastener 7a.
Also, in the present embodiment, the signal 81b of the signal 81a and B phases for the A phases that sensor portion 8 detects level one
The time point coaxial 71 of cause invades the time point of the groove 634 between two teeth 633 circumferentially-adjacent in multiple teeth 633 to greatest extent
Unanimously.Therefore, in the state of stopping rotary body 6 by snap fastener 7a, the signal of the signal 81a and B phases of A phases can be made
81b level is consistent.Also, in the present embodiment, in the angle position of permanent magnet 65 of the side of rotary body 6, the side of rotary body 6
Engage in the angle position of gear 63 and the angle position of axle 71, be provided with permanent magnet 65 for adjusting the side of rotary body 6
The angular position adjusting mechanism 7c of angle position.Therefore, it is possible to make the letter of the signal 81a and B phases of the A phases of the detection of sensor portion 8
Number 81b level consistent time point coaxial 71 invades between two teeth 633 circumferentially-adjacent in multiple teeth 633 to greatest extent
The time point of groove 634 is consistent, and enables to the time point that engaging is felt to be overlapped with exporting the time point of pulse 85.Also, root
According to angular position adjusting mechanism 7c, the angle position of rotary body 6 can be made to be overlapped with exporting the time point of pulse 85.Particularly exist
In the case that sensor portion 8 has used permanent magnet 65 and magnetic sensor element 56, due to can't see magnetic in magnetic scale (permanent magnet 65)
Above-mentioned time point is overlapped when changing position, therefore assembling more difficult, but due to that can be adjusted according to angular position adjusting mechanism 7c
The angle position of whole permanent magnet 65, therefore permanent magnet 65 is easily arranged on to optimal angle position.
Also, in the present embodiment, relative to sensor portion 8, overleaf side L2 is provided with the biography that is formed by magnetic material
The magnetic shield that the base plate 521 of sensor housing 52 is formed.Therefore, even in by the rear side L2 of manual pulse generating unit 1
Machining center etc. is installed on by magnet in the case of being operated, can also relax magnet by magnetic shield to sensor
The influence in portion 8.Also, side of the cylindrical body part 522 of sensor housing 52 as magnetic shield covering sensor portion 8.Cause
This, effectively can carry out magnetic screen to sensor portion 8.On the other hand, in supporting mass 200, due to closing cylindrical body part 522
The sensor enclosure 51 of opening be (nonmagnetic substance) being formed from a resin, therefore sensor enclosure 51 can be made by light and honest and clean
The material of valency is formed.Also, because sensor enclosure 51 is formed from a resin (nonmagnetic substance), therefore easily make sensor enclosure
51 turn into and are adapted to hold magnetic sensor element 56 or keep the structure of the grade of axle retainer 53 for snap fastener 7a.
